    Fix boost detection with autotools
    
    Turns out when BOOST_DIR is set in the environment
    the m4 macro looks for boost in BOOST_DIR/staging.
    Not what I expected. To have it look in the root
    of the installed directory, we need ac_boost_dir. However
    our cmake files do look in BOOST_DIR. So I'm simply
    setting both here.
